Definitions
- the invention relates to a device for operating a closure element or sun protection and a method for controlling the operation of such an element.
- Closure element means a door, a gate leaf, a shutter, a grid or equivalent equipment.
- solar protection element means a sun protection screen, store or equivalent type.
- motorized actuators generally comprise a device for stopping the movement of the closure element or sun protection in its end positions.
- facilities which, to stop the aforementioned element in its end positions, comprise a stop disposed on its path, and a meter continuously measuring the distance traveled by this element.
- the counter makes it possible to know when the element is in an area close to its end-of-travel position, for example a few centimeters from this position. In this area, the safety procedure is inhibited, in whole or in part, to make room for a simple procedure for stopping the closure element or sun protection. When the displaced element comes against the stop, the magnitude observed exceeds the setpoint and the element is stopped.
- GB-A-1,538,258 and US Patent 3,764,874 disclose installations in which the magnitude that varies with the actuating force is the mechanical tension of a motion transmission chain from an engine to a garage door. A contact is used to, when the screen arrives near its end positions, switch the so-called safety procedure in stop procedure.
- US Patent 5,668,451 provides to adapt the response of a safety device according to the rigidity of an obstacle encountered by a window or an electric sunroof. This security device is not able to handle limit switches.
- the invention intends to remedy more particularly by proposing a new device for maneuvering a closure or sun protection element whose commissioning is particularly simple and which makes it possible to ensure both the safety of persons and / or equipment in the vicinity of the moving area of the displaced element, as well as stopping when it reaches one of its end positions.
- the invention relates to a device for operating a closure or sun protection element, this device comprising means for driving this element between two end-of-travel positions, as well as a control unit for these drive means, this unit being able to act on these means to interrupt and / or reverse their operation as a function of the value and / or the variation of a parameter representative of an interaction between this element and an obstacle on the trajectory of this element between the two aforementioned positions.
- This device is characterized in that the drive means comprise means forming a stop and able to limit the displacement of this element at one of its extreme positions, in that the limitation of this displacement by these means forming a stop induces a variation of this parameter, in that the control unit can differentiate a variation of the aforementioned parameter, representative of an interaction of the aforementioned element with an obstacle, of a variation resulting from the action of the means forming an abutment and in that this unit can command differently the means according to the result of the aforementioned differentiation.
- the control unit thus makes it possible, by virtue of the differentiation it operates, to provide both an anti-collision safety function and a stop function of the closure element when it arrives in one of the either of its end positions, without the need for a meter or switch.
- the commissioning of such a device is therefore simple and fast and its cost is more attractive than that of known equipment.
- the differentiation can be performed on the basis of the duration of a variation of the parameter which corresponds substantially to a stop of the drive means.
- FIG. 1 to 3 The installation shown in Figures 1 to 3 is intended to move a leaf 1 between an open position, shown in solid lines and a closed position shown in phantom, where the leaf closes an opening defined between two pillars 2 and 2 '.
- the leaf 1 pivots about a vertical axis Z 1 defined by a lug 21 secured to the pillar 2.
- the leaf 1 is driven by an electric jack 3 itself articulated about an axis Z 3 parallel to the axis Z 1 and defined by another lug 22 carried by the pillar 2.
- the rod 31 of the jack 3 is hinged, about an axis Z 31 parallel to the axis Z 1 , on a lug 11 carried by the leaf 1.
- a control unit 4 makes it possible to control the movements of the leaf 1 by appropriately driving the jack 3.
- the jack 3 comprises a casing 32, one end 32a of which is articulated on the lug 22 and in which is disposed an electric motor 33, for example a direct current motor, supplied with current I by unit 4 by means of a multiconductor cable 41.
- an electric motor 33 for example a direct current motor, supplied with current I by unit 4 by means of a multiconductor cable 41.
- the output shaft 34 of the motor 33 is threaded and screwed into an internal thread 31a of the rod 31 which is immobilized in rotation and whose end 31b is hinged to the lug 11, as explained above.
- An encoder 35 makes it possible to detect the instantaneous angular position ⁇ of the rotor of the motor 33 and transmits the corresponding information to the unit 4 in the form of an electric signal S 1 ( ⁇ ) by means of a conductive cable 42.
- the method of processing the data inside the unit 4 comprises a first step 1001 in which the speed of rotation is calculated from the signal S 1 ( ⁇ ).
- ⁇ d ⁇ ⁇ d ⁇ t engine 3.
- the unit 4 calculates the variation of the speed ⁇ as a function of time, ie d ⁇ ⁇ d ⁇ t .
- a third step 1003 the absolute value of this variation is compared to a first predetermined value V 1 representative of the speed variations occurring normally during the opening and closing movements of the leaf 1 between its end positions represented respectively in full lines and in phantom lines in Figure 1.
- V 1 a first predetermined value representative of the speed variations occurring normally during the opening and closing movements of the leaf 1 between its end positions represented respectively in full lines and in phantom lines in Figure 1.
- the speed ⁇ can vary along the path of the leaf 1, in normal proportions.
- the value V 1 is chosen so that it can be considered that the operation is normal when the absolute value of d ⁇ / dt is less than this value.
- steps 1001 to 1003 are repeated and unit 4 continues to supply the motor 33 normally.
- ⁇ t depends on the catching up of the games at the joints of the jack 3 on the lugs 11 and 22, as well as on the level of the hinge of the leaf 1 on the pillar 2 and at the interfaces between the rod 31 and the 34 and between the internal components of the engine 33. In practice, the value of ⁇ t is of the order of 300 milliseconds.
- An abutment 36 in the form of a flange is fixed around the rod 31 inside the housing 22 and intended to bear against a cover 37 of the housing 32 when the jack is fully deployed, that is to say when the leaf is in the closed position, as shown in Figure 3.
- the sensor 35 is also used to detect the stopping of the motor 33 when the stop 36 hits the cover 37.
- the variation of the speed of rotation ⁇ between its normal value ⁇ n and the value ⁇ 0 representative of a stop occurs on a time interval ⁇ t much shorter than in the previous case.
- the value of ⁇ t in this case is of the order of 20 milliseconds. Indeed, no backlash of play occurs at the joints between the cylinder 3 and the lugs 11 and 22 or between the leaf 1 and the pillar 2, so that the variation in the speed corresponding to the stopping of the engine 33 is much faster.
- the duration of variation ⁇ t is lower when the stop 36 comes into action to differentiate a stop of the motor 33 due to an interaction of the leaf 1 with an obstacle of a stop due to the implementation of the stop 36.
- the value of ⁇ t defined above is compared with a predetermined reference value ⁇ T, for example equal to 100 milliseconds.
- ⁇ T a predetermined reference value
- the unit 1004 can be programmed to, in a step 1005, control the stopping of the motor 33 which has then reached its end position corresponding to the closing of the leaf.
- the unit 1004 can be programmed to control, in a step 1006, a reversal of the direction of movement of the motor 33, that is to say of the leaf 1 to release an obstacle struck. by this leaf.
- the abutment 36 and the cover 37 constitute the intrinsic stop means of the maximum extension movement of the jack 3. No part must therefore be added to the jack 3 to provide the stop function used in the invention.
- the cylinders are generally delivered in fully deployed configuration, that is to say in a configuration where their intrinsic stop is active.
- the measurement of the speed ⁇ can be carried out directly by an optical type or hall effect encoder, by measuring the back EMF of the motor in the case of a DC motor, or by any other known means.
- the parameter used by the unit 4 to detect its variations may also be the torque developed by the motor 33 during the maneuver, this torque being measured by the motor supply current.
- the measurement of the torque can also be performed by measuring the phase shift in voltage or current between motor windings.
- two abutments 36 and 36 ' can be mounted on the rod 31 of a jack 3, which makes it possible to detect the arrival of leaf 1 in its two open and closed end-of-travel positions. stops 36 'and 36 then respectively bearing against the cover 37 of the housing 32 of the cylinder. One can then act according to step 1005 in these two positions.
- FIGS. 7 and 8 elements similar to those of the first embodiment bear identical references increased by 100.
- This installation allows the operation of a sectional garage door 101 between a closed position shown in solid lines and an open position shown in phantom.
- the door 101 is connected to a carriage 105 moving back and forth parallel to the ceiling 102 of a building.
- the carriage 105 is connected to the door 101 by an arm 106 which is articulated on a tab 111 and on a tab 151 respectively integral with the door 101 and the carriage 105.
- the carriage 105 is driven towards and away from the lintel 121 of the opening to be closed by means of a drive device 103 which comprises an endless chain 131 disposed inside a rail 132 and driven by a electric motor 133 whose output shaft is engaged with a pinion gear 134 around which is wound the chain 131 about 180 °, while a second pinion 134 'is mounted loosely on the rail 132, away from the pinion 134.
- a drive device 103 which comprises an endless chain 131 disposed inside a rail 132 and driven by a electric motor 133 whose output shaft is engaged with a pinion gear 134 around which is wound the chain 131 about 180 °, while a second pinion 134 'is mounted loosely on the rail 132, away from the pinion 134.
- a connecting nut 138 is fixed on the chain 131 while being secured to the carriage 105, which makes it possible to reciprocate the carriage 105 as a function of the rotation printed by the motor 133 to the pinion 134.
- An encoder 135 is coupled to the motor 133 and makes it possible to detect the instantaneous position ⁇ of its rotor.
- the output signal S 1 ( ⁇ ) of the encoder 135 is transmitted, by a conducting cable 142, to a control unit 104 which supplies the motor 133 with its drive current I by means of a multicore cable 141.
- a thrust shuttle 136 is fixed on the chain 131. It is intended to bear against a stop 137 mounted in an adjustable manner on the rail 132.
- the shuttle 136 and the stop 137 are positioned respectively on the chain 131 and on the rail 132 so that the abutment 136 bears against the abutment 137 when the carriage 105 reaches the end of the stroke when closing the door 101, that is to say when the door 101 reaches its configuration shown in solid lines at Figure 8, from that shown in phantom.
- the stop 136 is closer to the motor 133 and the encoder 135 than the lower panel 112 of the door 101.
- the abutment 137 is positioned so that, when the shuttle 136 bears against this abutment, the chain portion separating this shuttle 136 from the pinion 134 is very short, in practice as short as possible, which makes it possible to preserve the ⁇ t interval corresponding to that shown in Figure 5 for the first embodiment a low value, for example less than 20 milliseconds.
- a second shuttle 136 ' can be mounted on the chain 131, a second stop 137' then being mounted at a suitable location on the rail 132 to stop the operation of the motor 133 at the end of the race.
- the shuttle 136 is remote from the abutment 137 and is in the cut portion of the rail in this figure.
- the control unit determines whether a parameter exceeds a threshold value, regardless of the temporal variation of this parameter. For example, if the detected parameter is the torque C generated by a motor, this torque varies in increasing until it exceeds a first value C 1 when a leaf or a door hits an obstacle. When the leaf or the door reaches a limit position, the torque varies in ascending order to exceed a second value C 2 , greater than C 1 because the damping of the locking effect of the leaf or the door is less than when interacting with an obstacle. By measuring the value of the torque C and determining whether it is between C 1 and C 2 or greater than C 2 , it is therefore possible to differentiate the causes of increase of this torque and to act accordingly on the motor. 'training.
- a method in accordance with the invention thus comprises a step 1003 where the value of C is compared with C 1 and where normal operation is conserved as long as C remains less than or equal to C 1 . If C exceeds C 1 , a differentiation step 1004 is carried out by comparing C with the value C 2 . If C is less than C 2 , then it can be considered that the displaced element has encountered an obstacle and the operation of the drive means is reversed in a step 1006. If C is greater than or equal to C 2 , then we can consider that the element reaches the end of the stroke and the drive means are stopped in a step 1005.
- the invention makes it possible, by means of a single control unit 4 or 104, to carry out two differentiated operations for controlling the movements of a closure element or sun protection element, namely the control of a movement in the opposite direction when an obstacle is encountered on the trajectory of this element or the control of the stopping of the motor when the element reaches an end position, the differentiation between the two actions to be undertaken being performed on the basis of the variation mode of the parameter used.
